Proguard混淆后，Google Drive API无法正常工作 [英] Google Drive API is not working after Proguard obfucation

问题描述

我正在使用

compile 'com.google.android.gms:play-services-auth:10.0.1'
compile 'com.google.android.gms:play-services-drive:10.0.1'

在我的Android应用中实现Google云端硬盘.在我用Proguard混淆应用程序之前，该应用程序运行良好.混淆应用程序后，尽管我尝试启用Google Drive备份选项，但该应用程序会弹出帐户选择"对话框，此后将不再继续.

to implement Google Drive in my Android app. The app is working well until i obfuscate the application with Proguard. Once the application is obfuscated, while i try to enable Google Drive Backup option, the app pop-ups the account selection dialog and doesn't proceed after that.

在该应用程序的调试版本中，当我尝试启用Google Drive备份选项时，该应用程序弹出帐户选择，然后进入Google Drive权限对话框以访问驱动器文件.

In the debug version of the app, while i try to enable Google Drive Backup option, the app pop-ups the account selection and then proceed to Google Drive Permission dialog to access the drive files.

我已阅读到Google为Google Play服务添加了Proguard规则，并且想知道我的情况可能是什么问题.我还尝试了以下StackOverFlow线程

推荐答案

如此处所示，您可以检查得到了什么通过查看ProGuard 输出文件将其删除.也基于此博客 ，这绝对是Proguard的问题.还注意到，其中一个调试语句表明文件对象具有一些可能引起问题的混淆字段. 快速浏览类文件，发现该类具有一些注释，并且我们在Proguard中看到了用于保留注释的引用.

As suggested here, you can check what gets taken away by looking at the ProGuard output files. Also based from this blog, it was definitely a Proguard problem. It was also noticed that one of the debug statements indicated that the Files object had some obfuscated fields that were probably causing a problem. A quick look at the class file showed that this class had some annotations and we’d seen references in Proguard to keep annotations.

如果有帮助，您也可以检查线程.
